JAMES DANIEL KENNON, OF DUKE, TEXAS.

CENTRIFUGAL MACHINE.

SPECIFICATION forming part of Letters Patent No. 737,416, dated August 25, 1903.

Application filed June 2, 1903. Serial No. 159,739. (No model.)

To all whom it may concern:

Be it known that 1, JAMES DANIEL KENNON, of Duke, in the county of Fort Bend and State of Texas, have invented a new and useful Improvement in Centrifugal Machines, of which the following is a specification.

My invention relates to centrifugal machines employed as sugar-driers to separate the molasses from the crystallized sugar by centrifugal action within a rapidly-rotating and perforated cylinder.

My invention consists in the means for introducing the sugar, washing the same, and then discharging it in a very convenient, rapid, and effective way, as will be hereinafter fully described with reference to the drawings, in which- Figure 1 is a plan view; Fig. 2, a vertical longitudinal section; Fig. 3, a vertical transverse section on line 3 3 of Fig. 2. Fig. 4. is a sectional detail of the centrifugal cylinder, and Fig. 5 an outside View of said cylinder.

My drier is erected upon a suitable base A, having a running-board A along the side and another one A at the end. The drier has an outer casing of sheet metal composed of two detachable semicylindrical sections B and B, the upper section B of which has a longitudinal opening 1) running nearly its full length, which opening has upturned flanges 12 I) along its sides. Over this opening a hinged door 13 is arranged to close, which door is connected bya cord b passing over a pulley b to a counterbalance If, so that the hinged cover may be conveniently raised and lowered with the application of but little power. are two uprights C C, which are connected at the top by a horizontal bar 0 from which are supported a series of funnels D,whose lower ends are in a row immediately above the opening in the casing and through which funnels the sugar in a semiliquid condition is fed into the machine.

The working parts of the machine consist of a coarsely-perforated outer cylinder E,having a lining E of wire netting and inside of this a finely-perforated lining E Through these several layers E E of the cylinder there are formed openings e, that register with the funnels D above when the cover of the case is raised and through which the sugar gains ac- At the rear side of the casing there cess to the interior of the centrifugal cylinder.

These openings 6 are closed by a rotary gate consistingof two rings F F, connected by longitudinal bars ffand a cut-off plateF. This forms a rotary swiveling gate that turns about the periphery of the cylinder between collars F F fixed exteriorly on the cylinder, which hold the rotary gate against endwise movement. This rotary gate may be turned about the axis of the cylinder, so as to uncover the openings 6 to admit the sugar, andis then turned back by a swiveling movement to cause the cut-off slide-plate F to pass over the holes 6 after the sugar is in. This rotary gate after being closed is held against accidentally turning by hook shaped spring -catches e, which engage the longitudinal barsf of the gate and securely hold them against turning in both directions. This form of gate permits the centrifugal cylinder to be rotated at high speed without danger of opening the gate. The cylinder E turns at one end upon a circumferential bearing within a ring G and at the other end has a hollow shaft H, which turns in a bearing G, and on the outer end of said hollow shaft has a 1n ultiple-groove pulley I, adapted to receive a number of cable-belts from a similar pulley on a driveshaft. The hollow shaft H opens at its end through the pulley I and is adapted to receive a hose-pipe P for the introduction of water or connects with a coupling from an air-pipe P for a blast of air, as hereinafter described. The opposite or discharge end of the cylinder is closed by a large door-valve J,

mounted on the end of a horizontal lever J. By swinging this lever about its fulcrum the end of the cylinder maybe left open or closed, as may be desired. To hold this valve and lever in eitherZof their adjustments, a set-1ever J is arranged with a pinching-head 3' about the fulcrum of lever J, so that when the set-lever is turned it will pinch and hold the lever J, carrying the valve in either the open or closed position. The upright O of the framework is mounted to turn about a vertical axis, and it carries an arm 0 in which are supported a flexible hose-pipe P and a larger metal pipe P. The flexible hose-pipe is for the introduction of water or chemicals, and the pipe P is for introducing a blast of air, and they are constructed to be alternately fitted to a central pipe arranged within the cylinder. This central pipe has its outer portion K imperforate and its inner portion K perforated, and between 4 these two sections is an enlarged transverse air-drum K having in its ends spring-valves k opening outwardly. The inner end of the central pipe is supported centrally by radial armsk 70 At one end of the casing there is a syrup-spout L, through which the molasses is conducted away, and at the other end there is a chute or flange L to direct the discharge of the sugar when it is to be removed from the cylinder.

The operation of my drier and separator is.

as follows: The sem'ifiuidsugaris introduced into the cylinder through the funnels and the opened hinged cover-and the openings e in the cylinder. The openings 6 are then closed by turning the swiveling gate and the latter locked in place. The valve at the discharge end of the cylinder is then closed and the cover of the case let down, and a high rotary speedbeing imparted to the cylinder through the cable-belts centrifugal action causes the syrup to pass through the perforations of the cylinder, while the crystallized sugar remains in the cylinder. This syrup fiows away at the spout L. To wash the sugar, astream of water, with or without any purifying agent, is introduced through pipe P and is allowed to issue through the perforations in the section K of the central pipe and passes through the sugar and goes out with the syrup. After the sugar has been washed and dried by centrifugal action the pipe P is disconnected and the air-pipe P is connected to the central shaft and the discharge-valve at the other end of the cylinder is opened. A powerful blast of air is then introduced through pipe P, and as it enters the drum K it opens the spring-valves 70 71: and also passes through the perforated section of the central pipe, with the result that the dry granulated sugar is quickly blown out of the end of the cylinder, thus saving the slow, tedious, and laborious way of removing the sugar, as heretofore practiced.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A drier comprising a perforated centrifugal separator havinga valved end, and feedinlets along the side, a hollow shaft entering said cylinder, an air-blast pipe, and a coupling adapted to connect it with the hollow pipe to blow the dried material out of the separator substantially as described.

2. A sugar-driercomprising a perforated centrifugal separator having one end open, a valve or door for said open end, a hollow shaft arranged within the separator and made with one part perforated, another part imperforate,and an air-dru m between said parts With outwardly-opening spring-valves, two interchangeable pipes, one for water and the other for air, said pipes being arranged to connect alternately with the hollow shaft to first wash the sugar and then blow the same out of the separator substantially as described.

3. In a sugar-drier, a perforated centrifugal cylinder having one or more lateral'feedopenings along its side, combined with a ro-.

tary swiveling gate turning about the longitudinal axis of the cylinder to close said feedopenings, and means for locking said gate, substantially as described.

4. A sugar-drier comprising an outer casing havinga longitudinally-arranged door at the top and a molasses-spout at the bottom, a perforated centrifugal separator arranged within the casing and provided with one or more feed-openings along its side, a gate for closing said openings, a framework provided with one or more filling-funnels located above said feed-openings, and means for rotating the separator substantially as described.
